title: Effects of naloxone therapy on hemodynamics and metabolism following a superlethal dosage of Escherichia coli endotoxin in dogs.
abstract: Experiments were done upon anesthetized and unanesthetized dogs given endotoxin only, endotoxin plus naloxone or naloxone only. Dogs given endotoxin and treated with naloxone showed marked hemodynamic and metabolic improvements compared with the dogs given endotoxin only. Beneficial effects of naloxone treatment following the administration of endotoxin are attentuated hypotension, hemoconcentration and acidosis and prevention of hypoglycemia. Results of mortality studies in unanesthetized dogs given endotoxin suggest that naloxone treatment increases the survival time.
